Policy currently uses "must not install" and "should not install" many
times over, with the same meaning.

If you're suggesting an ambiguity between "must not install" (as part of
the package) and "must not write" (at runtime), as far as I can tell
Policy generally uses "write" for things done by software at runtime,
and in such cases refers to things like "applications", "programs", or
"software", rather than "packages".
